There are a bunch of "deals" out there on reloading presses. I would recommend getting a Lee kit, which costs about $150 for a basic single stage press and other items needed to get started. There are a lot of Lee haters out there but I have been using the same one since about 1972. For about a total of $250 you can be loading one caliber. That is the low end of initial start up.
I also have a Dillon progressive press with manual indexing (RL 550 B). Now you are talking the high end of initial startup with about $600 spent!!
